Hum
Bug 50/60 Hz Noise Eliminator
A New Solution
A new approach to Noise Control. This is a powerful new technology for
cancelling electrical interference in real-time, avoiding all of the
traditional problems associated with notch filters. The Hum Bug
constructs a replica of noise present on the input signal and
continuously subtracts this replica from the signal as it passes through
the instrument. It performs this function in the presence of biological
activity even when noise characteristics evolve over time.
Advantages
The HumBug is not a filter. It does not create phase delays, amplitude
errors, DC shifts or waveform distortion. Simply connect it between your
preamplifier and any analysis equipment and it will automatically
eliminate 50/60 Hz noise and harmonics with frequencies up to several
kHz. Noise is eliminated without altering the signal of interest even
when frequencies within the signal overlap with noise components. No
settings or adjustments are required.
